Is f(x) Builder Safe to Use in 2026?
Generally Safe
Score 85/100f(x) Builder has no known CVEs and is actively maintained. It's a solid choice for most WordPress installations.
The fx-builder plugin version 1.0.2 exhibits a generally good security posture based on the provided static analysis. It demonstrates adherence to secure coding practices by utilizing prepared statements for all SQL queries and implementing nonce and capability checks on all identified entry points (AJAX handlers). The absence of dangerous functions, file operations, and external HTTP requests further contributes to its security. The low percentage of unescaped output is a minor concern but not a critical one given the overall context.
The taint analysis revealed no critical or high-severity flows, indicating no readily identifiable pathways for data manipulation or code execution through unsanitized inputs. The vulnerability history is also clean, with no recorded CVEs. This suggests that, at least in its history, the plugin has not been a source of significant security flaws. While the plugin performs well in these areas, the slightly lower percentage of properly escaped output warrants attention as a potential, albeit minor, area for improvement to further harden the plugin against cross-site scripting vulnerabilities.
In conclusion, fx-builder v1.0.2 appears to be a relatively secure plugin with a strong foundation in secure coding principles. The absence of critical vulnerabilities in both static analysis and historical data is a significant positive. The primary area for improvement lies in addressing the unescaped output, though the current rate is not alarmingly high. Overall, the risk associated with this plugin is assessed as low.
